The Colorado AI Act (SB 24-205) was the first comprehensive state AI law in the country. Enacted May 17, 2024, it required developers and deployers of high-risk AI systems to use reasonable care to protect consumers from algorithmic discrimination. High-risk systems were those that make or substantially influence consequential decisions in areas like employment, housing, lending, insurance, education, and healthcare.
What the Colorado AI Act Required
Duties included impact assessments, risk management programs, and consumer notices when AI was involved in a decision. Covered companies also faced disclosure obligations to the Colorado Attorney General.
Repealed and Replaced Before Enforcement
The core obligations were originally set for February 1, 2026, and were pushed to June 30, 2026 by SB 25B-004. The law was then repealed and replaced by SB 26-189 in May 2026, before enforcement began. Businesses should treat SB 26-189, not SB 24-205, as the operative Colorado framework going forward.
